preparation example Construction

[0032] A method for preparing an antibacterial fully degradable plastic material based on extracts of Chinese herbal medicines, comprising the following steps;

[0033] Step 1: crush the leaves of mugwort and pomegranate peels separately, pass through a 2-mesh sieve, and mix according to a certain mass ratio to obtain a compound Chinese herbal medicine powder, wherein the leaves of mugwort account for 50-90% and the peel of pomegranates accounts for 10-50%;

[0034] Step 2: Add the compound Chinese herbal medicine powder in step 1 into tap water according to the mass (Kg) volume (L) ratio of 1:5-1:20, mix evenly, and stir and extract at 100°C for 20-90 minutes;

[0035] Step 3: centrifuging the extract in step 2 to obtain the extract supernatant;

[0036] Step 4: Mix and stir PBAT particles with 0.5-2% coupling agent, 0.5-2% solubilizer, 0.5-2% heat stabilizer, and 0.01-0.2% antioxidant to obtain PBAT mixed material liquid, and The supernatant of step 3 is added to the PBAT mix...

Abstract

The invention discloses an antibacterial full-degradable plastic material based on a Chinese herbal medicine extract. The antibacterial full-degradable plastic material comprises the following components: folium artemisiae argyi, pomegranate rind, PBAT, PLA, a coupling agent aluminate, a solubilizer stearic acid, a heat stabilizer epoxidized soybean oil and an antioxidant 1010. The preparation method comprises the following steps: respectively crushing and mixing folium artemisiae argyi and pomegranate rind, adding tap water, uniformly mixing, extracting supernatant liquid, adding the supernatant liquid into PBAT mixed material liquid, continuously mixing and stirring at a high speed, and then drying to obtain the master batch. According to the antibacterial full-degradable plastic material based on the Chinese herbal medicine extract, folium artemisiae argyi and pomegranate rind are used as Chinese herbal medicine components, the Chinese herbal medicine extract is obtained through high-temperature water extraction, the extract and a PBAT component are mixed, the extract is loaded and distributed into a PBAT material by means of mixing distribution and high-temperature protection effects of a coupling agent, a solubilizer and a protective agent, and the antibacterial full-degradable plastic material based on the Chinese herbal medicine extract is obtained. And further mixing with a PBAT / PLA composite material to prepare the antibacterial plastic material which contains Chinese herbal medicine components, has an antibacterial function and can be completely degraded in the environment.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an antibacterial fully degradable plastic material based on extracts of Chinese herbal medicines and a preparation method thereof. Background technique [0002] With the continuous improvement of people's demand for food quality, safety and hygiene and the advocacy of green packaging concepts, antibacterial materials have been widely used in food packaging. Antibacterial materials are a general term for new functional materials that have antibacterial and bactericidal properties and antagonize microorganisms. By adding or compounding one or several specific antibacterial components (antibacterial agents) to ordinary materials, the antibacterial properties of materials are obtained and enhanced. . Antibacterial plastic is the fastest growing, highest premium and most widely used packaging material among antibacterial materials. When ordinary plastics are endowed with a...
